Observational Study of Rebismart®2.0 + MSdialog™ in Subjects With Remitting Multiple Sclerosis (ADHERQOL)...
Multiple SclerosisRelapsing-remittingThis is a 24-month, observational, prospective, multinational, multicenter study to determine the relationship between the relapse (percentage of relapse free subjects) and adherence in subjects diagnosed with RRMS treated with Rebif (interferon beta-1a) using the RebiSmart®2.0 and MSdialog™.
Evaluation of Pulmonary Doppler Signals in Patients With Systemic Sclerosis(SSc)
Systemic SclerosisPulmonary HypertensionDoppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package- the Transthoracic Parametric Doppler (TPD) (Echosense Ltd., Haifa, Israel). Systemic sclerosis patients often develop pulmonary vascular disease leading to pulmonary hypertension. The TPD system may provide important insight into pulmonary blood vessels characteristics by the LDS (Lung Doppler Signals) signals that are related to pulmonary hypertension. The TPD performance in detecting PAH in SSc patients will be assessed in the study.
Magnetic Resonance Imaging (MRI) in Amyotrophic Lateral Sclerosis (ALS)
Amyotrophic Lateral Sclerosis (ALS)This is a pilot study to identify the degree of grey and white matter involvement in patients with Amyotrophic Lateral Sclerosis (ALS) utilizing non-invasive techniques. The imaging to be utilized will be the 7 Tesla (7T) magnetic resonance imaging (MRI) of the brain. These results will be correlated to the ALS Functional Rating Scale - Revised (ALSFRS-R) score to assess if any changes in MRI can be predictive in the disability of the ALS patients at baseline and at 6 month intervals. The participants will be asked to return every 6 months for a neurological examination, ALSFRS-R assessment, measurement of the vital capacity and MRI as outlined above to monitor progression of the disease.

LEMTRADA Pregnancy Registry in Multiple Sclerosis
Multiple SclerosisPrimary Objective: The primary goal of this registry is to assess the risk of spontaneous abortion in prospective enrolled women exposed to LEMTRADA for multiple sclerosis. Secondary Objective: The secondary goals of this registry is to assess maternal, fetal and infant outcome in women with multiple sclerosis, exposed to LEMTRADA.
Efficacy of COVID-19 Vaccination in Patients With Multiple Sclerosis Treated With Immune Modulating...
Multiple SclerosisThe primary objective is to determine whether the use of immunomodulating medications have an impact on the ability to mount and sustain an immune response to SARS-CoV-2 spike protein following mRNA vaccination in patients with MS when compared to healthy controls not receiving immunomodulating medications. We hypothesize that the use of immunomodulators in MS patients may eliminate or reduce the level of protective immune response, and/or shorten the duration of the protective response.
Canadian Multicenter Observational Study of Tysabri in Early Relapsing Remitting Multiple Sclerosis...
Relapsing-Remitting Multiple SclerosisThe primary objective of the study is to evaluate the impact of early treatment with Tysabri in Relapsing Remitting Multiple Sclerosis (RRMS) participants on their quality of life (QoL) as measured by Multiple Sclerosis Impact Scale-29 (MSIS-29) over 2 years. The secondary objectives of the study are: to evaluate the impact of early treatment with Tysabri in RRMS participants over 2 years on the following: annualized relapse rate (ARR), Expanded Disability Status Scale (EDSS), work productivity, quality of life (QoL) by EuroQol 5-Dimension questionnaire (EQ-5D), QoL by Subject Global Assessment of Wellbeing visual analog scale (VAS) and to evaluate clinical disease-free status (relapses, EDSS) over 2 years.
Restoring Glutathione Synthesis With Tecfidera: An in Vivo H-MRS Single-Arm Study at 7T in Patients...
Multiple SclerosisThe primary objective is to directly estimate brain glutathione concentrations in vivo using H-MRS at 7T before and after initiation of Tecfidera in established multiple sclerosis (MS) patients considering switching therapy or being treatment-naive (first line).
Amyotrophic Lateral Sclerosis and Frontotemporal Dementia
Frontotemporal DementiaAmyotrophic Lateral SclerosisAmyotrophic lateral sclerosis (ALS) with frontotemporal dementia (FTD) is a rare clinical entity, in which both disorders are variably associated in the same patient or within the family. This adult-onset disorder, which is rapidly fatal, occurs in some families with autosomal dominant (AD) transmission and age-dependant penetrance. Two studies have provided evidence for linkage of this condition to chromosomes 15 (in a single family) and 9 (in five families). However, none of these loci have been yet confirmed. Through a national network of 10 centres with specialists for FTD and/or ALS, we have identified 35 probands with ALS-FTD, including 13 with a family history consistent with AD inheritance. Mutations in the SOD1 and tau genes, respectively responsible for autosomal dominant forms of ALS and FTD, will be excluded by direct sequencing. We will then extend the pedigree of the 13 autosomal dominant families to all consenting first, second and eventually third degree relatives, using well defined criteria for FTD and ALS. The same strategy will be applied to newly identified families during the course of the project (at least, seven families with AD inheritance expected). Linkage studies will be performed in the 20 families using markers from the two candidate regions on chromosomes 9 and 15. Then, refinement of the candidate region will be obtained by analyzing the linked families with a high density of microsatellite markers. This should lead to the refinement of the candidate regions, allowing to search for mutations in candidate genes. Genes located within the critical regions will be prioritized for their analysis by sequencing, according to their expression in the nervous system and to their function. Once the responsible gene(s) will be identified, it will then possible to define its spectrum of mutations and to establish genotype/phenotype correlations. Alternatively, if none of the candidate regions is confirmed, a genome wide search will be performed, allowing to identify one or more loci for ALS-FTD. The same strategy would then be applied to identify the corresponding gene(s). This project should contribute for identifying the molecular basis of this devastating disorder with practical consequences for genetic counselling in ALS-FTD families, and with the perspective of elucidating the pathophysiology of this disorder.
Baseline Cortical Haemodynamics in MS
Multiple SclerosisThis study will provide information on cortical haemodynamics in MS patients to address the discrepancies reported in previous literature, allowing further insight into the role of haemodynamics in the disease. It will also instruct us as to the most effective scanning protocols for future research. Developing a suitable protocol for studying perfusion longitudinally may also enable identification of new therapeutic interventions to normalise any perfusion abnormalities in MS patients.
